Amazon's ( AMZN ) Prime Day is set to see reduced participation from third-party sellers, especially those importing China-made goods, due to the impact of steep US-China trade tariffs, Reuters reported Monday.

The report said the pullback could lower Amazon's ( AMZN ) fees and advertising revenue for the event and limit discounted items' availability.

Amazon ( AMZN ) typically takes a 15% commission on each sale, not including fees for promotional placements like 'Best Deal' or 'Lightning Deal,' which can cost sellers $500 to $1,000, Reuters said.

Third-party sellers accounted for nearly 62% of units sold on Amazon ( AMZN ) in Q4 2024, Reuters said, citing e-commerce research firm Marketplace Pulse.

In 2024, US shoppers spent $14.2 billion during Prime Day, an 11% increase from the previous year, Reuters said, citing research firm Adobe Analytics.

While Amazon ( AMZN ) has not set a date for Prime Day 2025, it has confirmed the event will span four days in July, the report said.

"We're working with our broad, varied range of valued selling partners in our store to support them in adapting to the developing environment while maintaining low prices for customers," an Amazon ( AMZN ) spokesperson said in an email to MT Newswires.
